Process for the hydrocracking of hydrocarbon feedstocks

A hydrocracking process:A. hydrotreating HDT the feedstocks,B. gas/liquid separation of effluent from A with a separation device having a chamber compartmentalized into an upstream degassing compartment and a downstream stripping compartment, the passage of the degassed liquid from the degassing com...

Zusammenfassung:	A hydrocracking process:A. hydrotreating HDT the feedstocks,B. gas/liquid separation of effluent from A with a separation device having a chamber compartmentalized into an upstream degassing compartment and a downstream stripping compartment, the passage of the degassed liquid from the degassing compartment to the stripping compartment being provided by an opening made in the internal wall and/or by overflowing above the said internal wall separating the said compartments,C. hydrodesulfurization of gaseous effluent obtained in B and of an external feedstock,D. a first hydrocracking of liquid effluent resulting from B,E. gas/liquid separation of liquid effluent from D and of the liquid effluent from C,F. a fractionation of liquid effluent from E,G. a second hydrocracking of unconverted liquid fraction from F.
